Implemented New Features:

* Fixed the install target to install files correctly
* Implemented the uninstall target to remove files from install dirs
* Isolated the top level targets (dist, dist-check, dist-clean, tags) so
  they only run/exist from the top level directory
* Put if/endif gaurds around potentially dangerous $(RM) commands.
* Implemented place-holder rules for distribution targets to just say that
  they aren't implemented yet.
* Implemented tags target in Makefile.rules so all projects can use it
* Made a pony for resistor
